I'm not sure if a forwarder uses default window sizing or not (would be a good support question) but you are correct that there is no way to manipulate the window sizing in a FastL4 profile other than changing the TCP Window Scale Model to "Strip" (which I'm not sure what good that would do). Interestingly on a 9.4.3 box I'm looking at the online help also says you can set it to "Rewrite" however that option is not actually available in the drop-down box. That may be a bug in the help or the GUI, not sure which. I'm thinking this definitely deserves a support case to clarify this.
